I Y Application filed May 2,

ToaZZ whom it may oonce'flmf i l I l Be it knownthat I, DANIEL'MAGNY, 'cit1-' zen of the French Republic, residing at Issoudun, Indre, in the Republic of France, have invented new and useful Improvements in Machines for Setting and Mixing Pig Bristles, of which the following is a j specification. {l his invention has for its object a-machine for the preparation of pigbristles,

and serving in particular for the setting [and the mixing of, the bristles. The fsetting? consists,- as .is known, in disposing the bristles substantially parallel .to eachother andin suchmanner thattheir roots are all onthesam'e'sideL,

a" setting? drum French Patent No..-368009 'ofaApril 20th,

1906,- as well'as a device-for receivingthe set bristles, of a new construction.

The setting drumis formed' by a'fixed horizontal drum provided at the upperpart with one or more apertures*o-rifee'dingi ho-p pers; as fwell as with a chimneyfonthe evacuation of dust, and whereof the cylini drical wall is formed at the bottom by a perforatedsheet metal piece; in this fixed 'drurrris caused torot'ate a central shaft provided with two-1 series in: dian letral 0);)- position, of radial ,rods on teeth which their rotation. pass between the teeth :of one I or more stationary combs situate'd'at'the upper part of the drum, in such manner that the bristles placed in the drumar'e-projected in the air by the ventilating effect of the rotating-teeth,- will be separated from each" other upon encountering thequpe per fixed: teeth, and willfall down ,bythe action of gravity, whichjsets them upright andobliges themto pass through the perforated sheet metal piece ,with ,the'root downward. a

;Thereceiving device comprises'a set of passages slightly inclined with reference-to the verticaL-dispose'd below the perforated sheetgmetal piece and an endlessbeltwhich moves below these passages and upon which the bristles will lie down as-they fall; up'on theg'same after having passedvth'rough the perforatedsheet with the roots downward, the said belt extending outwardlyof the passages insuchmanner as --to afford;- an .un-

covered part wherefrom the operatormay take the bristles in, order to place them up- :Fg; 1 's a side elevation for setting a and mixing pig bristles cons structed according to-the inventi0n,'ithe set l ting i drum heing represented in, section; f Fig. 2 is an end view, the drumbeing also vseenuin section; I 1

This drum" .maylfor examp-le'fihave three metres-length andone metre ,diameteri It j is provided throughout the wholelengthiwith two clean-5i ing doors 2 and at the npperm part With] two feed hoppers 3 intowhich may he introduced-the bristles to-be set; A chimney v3* which is necessary for the evacuation of dust is-als'o provided at the'upperpart. a

An aspirator ,mayibe disposed at the end v ofQthe discharge pipe "of thisKchimneyfin order to eliminate ina'more complete -mannerthe dust and: other impurities of the bristles. Thelower; part of the; cylindrical wall of this; drum is formed by a perforated sheet metal piecee. The drumisdivided,

in the example represented, into three comof the 'lowerperforated" sheet f metal piece.

These rotating teeth also passin. their rotashaft ,5 carries at one endthe actuatingt pulleys 10 and at the iotherendapulley-11. v

' Below -.the- .drum 1. is "vino-mated.fa device? for receiving the-bristles, composed of-[ja series offpassages 12 of sheet metal or other, material, slightly inclined "with'refe'rence ot'o 1 the vertical;- :These passages-mayb have a rectangular or other section and may have for example. about .30 centimeters height in the part uThey =may be soldered or otherwise secured-together to form one nor a? a ldrum for setting the bristles co'nstituted more groups which are attachedbelow the drum through theintermediary of angle bars 13 and connecting members or bolts. The upper surface of the assemblage of p-assages 12 has a curved'form in order to correspond to the shape of the vperforated sheet metal piece 4. The lower surface of the assemblage of the passages lap-lane Below this lower surface is caused to move an endless belt or apron 14 of india rubber or other material, carried at its ends by two rollers 15 and 16. The shaft of the" roller 16 carries a gear wheel 17 in engagement with a worm 1S actuated by a pulley 19; which is connected by a belt 20 with the pulley 11 carried by the shaft 5 of the drum. The apron 14 thus receives a continuous forward movement. The upper strand of this apron is supported by small rollers- 25 mounted in supports 26. The shaft of the end roller 15 is carried by stretching been ings which may be displaced on the frame by means of screws 27 carrying the hand wheels 28. In this way the apron may be perfectly stretched in order to form a table.

The machine is operated as follows:

The setting of'the bristles is effected in the drum 1 in the following manner: The bristles introduced by small successive quantities into this drum are projected into the air by the'teeth 6 or by'the air current which they produce when rotating; they meetnear the upper part of the drum withtheteeth of the stationar combs '4 which se arate them and oblige them to fly about in the drum in such manner as to fall under the action of gravity,with the roots down, through the perforated sheet metal piece 4; The bristles which are thus set will descend in the passages 12 and will fall upon the endless apron 14: upon which they will lie flat, with the root in front by reason of the forward movement of this apron. By means of the latter, the bristles which are set'and laid down will themselves come in front of the operator who is stationed at the end of the machine and removes the bristles as fast as they are presented in order to place them upright. The-dust remaining on the table falls into a receptacle and is thus automatically removed. i

As will be observed, this receiving device occupies but a very smallspace and. is of a very simple construction and. operation.

The drum 1 being divided into several compartments by the partitionsS andthe perforated sheet metal piece a being made in several pieces, the cleaning may be carried out rapidly and conveniently by removing and cleaning the perforated sheet metal piece of one. of the compartments without interrupting the operation of the other two.

The machine described will permit a single female operator to prepare 100 kilogrammes of ig bristles perday; this amount ters Patent is:
